CONSECUTIVE-VIEW APPARATUS.

SPECIFICATION forming part of Letters Patent No. 597,759, dated January25, .1898.

Application file'd May 28, 1897 To all whom it may concern:

Be it known that I, HERM AN OAsLE'R, a citi-- zen of the United States,residing at Canastota, in the county of Madison and State of New York,have invented certain new and useful Improvements in Consecutive-ViewApparatus; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable others Toskilledin the art to which it appertains to make and use the same.

My invention relates generally to improvements. in consecutive-viewapparatus, and particularly to improvements in mutoscopes I 5 orpicture-exhibiting instruments designed to reproduce to an observer themotions of objects by passing before his eyes in rapid sudcession aconsecutive series of views of such objects; and my invention is animprovement upon the niutoscope illustrated and described in LettersPatent of the United States No. 549,300, issued to me on November 5,1895.

to n ln the mutosco ie of that patent the pictures ammm 'ataas ofresilient cards mount- 2 5 ed'radially upon a revolubly-mounted spool orreel, which is rotated by means of suitable gearing. A detent, locatednear the place from which the pictures are to be observed, engages theedges of the cards as the spool ro- 3o tates and retards them, holdingthe cards stationary, successively, in the field of view until by themovement of the spool each card is caused to bend sufficiently to slipunder the detent, when its resiliency causes it to spring 3 5 forward,passing so rapidly across the field of view that it does not perceptiblyinterrupt the vision and exposing to View the picture on the nextsucccedin g card. I have found that the resiliency of the picture-cardsthemselves is not always suflicien-ttognosge them acrossthe field ofview as rapidly as is desirable'j 'lliis is the case particularly wherethe picture cards are of considerable size and are formed ofcomparatively thin paper. In such cases,

therefore, it is desirable to provide means for accelerating themovement of the picturecards when passing across the field of view.

The object of my invention, therefore, isto provide acheap. simp e, andeilective device for accelerating the movement of the picturecards whilemoving across the field of view and causing them to move more rapidlythan they would be moved by their own unaided resiliency. This object Iattain by interspersing between the picture-cards other cards or platesofjhigh resiliency which, when released by the detent, move with thedesired speed across tlie'field of view and in so doing carry thepicture-cards with them.

My invention consists in the use of such auxiliary cards or plates ofhigher resiliency than the picture-cards and in the combination of thepicture-cards and carrier and connected mechanism therewith.

In the drawings, in which the same reference-numerals indicate the sameor corresponding parts, Figure 1 is a side elevation of the mechanism ofa mutoscope in which the cards are mounted upon a spool or reel, theside of the inclosing case having been removed. Fig. 2 is alongitudinal-section of thespool or reel with the cards thereon; andFig. 3 shows the invention applied to a 1nutoscope in which the cardsare mounted upon an endless band or belt, the inclosing case having beensectioned. 4

Referring first to Figs. 1 and 2, 1 is the inelosing case of themutoscope. 2 is the spool or reel carrying the cards and is mounted upona shaft 3, having suitable hearings in the case 1 and revolved by meansof a shaft 4; and crank 5 and connecting-gearing. (3 is theobservation-opening.

Upon the reel 2 are two series of cards 7 7 and 8-8. 7 are thepicture-cards, and S the auxiliary cards of high resiliency, abovementioned,which alternate with the picture-cards. The picture-cards maybe any cards suitable for having pictures imprinted or otherwise placedupon their faces, and the auxiliary cards may be composed of afinequalit Y of bristol-boardpr of the stock from which play- "nigarusmenac -o1- may becoinposed of some other higl'ily-resilientmaterial, such as thin metal or celluloid. In the drawings theauxiliaryicards are indicated by lines which are heavier than the lineswhich indicate the picture-cards,thus apparently indicating that theauxiliary cards are thicker thanthe picture-cards. This will naturallybe the case when the auxiliary cards are composed of paper; but if madeof metal they may be thinner than the picture-cards. l V

9 is the detent which holds back the vari- IOU screw-threads and areprovided with projections or tenons engaging notches in'thepicture-cards. The two parts of the reel may be secured together, so asto hold these cards very firmly.

In Fig. 3 the cards are shown mounted u pon' an endless beltor bandinstead of upon a 'lar type of mutoscope.

reel. This belt passes around pulleys 11 and 12, and a crank 5 isprovided to rotate one of these pulleys so driving the belt. I Asuitable detent 9 is also provided near the observation-opening 6. Thecardsrnay be fastened to the belt in any convenient manner.

I do not limit my inven tion-to any particu- The auxiliary cards of highresiliency may be employed in any consecutiveview apparatus whichdepends for its operation upon the resiliency of a se ries of cards.

The operation of the auxiliary cards is the same in whatever form ofapparatus they are employed. As the carrier for the cards is operatedthe picture cards and auxiliary cards are successively moved under thedet ent and when they have been bent sufficiently escape from under thedetent and spring forward across the field of view. Since eachpicture-card and its corresponding auxiliary card are held in closecontact by the detent, they will spring forward at substantially thesame time, the resiliency card carrying the picture-card rapidly acrossthe fiel of view. l z

Having thus completely described my'invention, what I claim, and desireto secure by Letters Patent, is-

1. Ina consecutive-View apparatus, the combination, with amovably-mounted carrier having'attached thereto aseries of cardsprojecting therefrom and adapted to carry interspersed between views,and means for operating the carrier, of a series of auxiliary cards orplates interspersed between said-picture-carrying cards and adapted toimpart resiliency thereto, and means for momentarily retarding andbending backward the cards of said carrier, successively, as the carriermoves, substantially as described.

2. In a consecutive-view apparatus, .the combination, with a'oarrierhaving a series of cards mounted thereon. adapted to carry views,andaseries of auxiliary cards or plates said view carrying cards andadapted to impart resiliency thereto, each card being free at one endand rigidly secured to the carrier at the other end,

of means for operating said carrier, and means for momentarily retardingand bending backward said cards, substantially as described.

3. In a mutosc'ope, the combination, with a reel, of a series ofpicture-cards arranged radially thereon, and a series of auxiliary cardsor plates interspersed between said picturecards and adapted to impartresiliency thereto, substantially as described.

4. In a mutoscope, the combination, with a reel having a series ofpicture-cards arranged radiallythereon, of a series of auxiliary cardsorplates interspersed between said picturecards and adapted to impartresiliency thereto, and means for rotating said reel, substantially asdescribed.

5. In a mutoscope, the combination, with a reel having a series of picture-cards arranged radially thereon, of a series of auxiliary cards orplates interspersed between said picturecards and adapted toimpartresiliency thereto, a detent for momentarilyretarding and bendingbackward said cards, successively,

as the reel moves, and means for rotating said reel, substantiallyasdescribed.

6. In a mutoscope, the herein -described auxiliary card or plate adaptedto impart resiliency to the picture-cards, substantially as described.

In testimonywhereof I afiix my signature in presence of two witnesses.
